Variation in symbiont density is linked to changes in constitutive immunity in the facultatively symbiotic coral, Astrangia poculata
<p>Scleractinian corals are essential ecosystem engineers, forming the basis of coral reef ecosystems. However, these organisms are in decline globally, in part due to rising disease prevalence. Most corals are dependent on symbiotic interactions with single-celled algae from the family Symbiodiniaceae to meet their nutritional needs, however suppression of host immunity may be essential to this relationship. To explore immunological consequences of algal symbioses in scleractinian corals, we investigated constitutive immune activity in the facultatively symbiotic coral, <em>Astrangia poculata</em>. We compared immune metrics (melanin synthesis, antioxidant production, and antibacterial activity) between coral colonies of varying symbiont density. Symbiont density was positively correlated to both antioxidant activity and melanin concentration. Our results suggest that the relationship between algal symbiosis and host immunity may be more complex than originally hypothesized and highlight the need for nuanced approaches when considering these relationships.</p>
Data from: Quantifying and linking mechanism scenarios to invasive species impact
<p>Plant species invasion represents one of the major drivers of biodiversity change globally, yet there is confusion about the nature of non-indigenous species (NIS) impact. This stems from differing notions of what constitutes invasive species impact and the scales at which it should be assessed. At local scales, the mechanisms of impact on local competitors can be classified into four scenarios: 1) minimal impact from NIS inhabiting unique niches; 2) neutral impact spread across the community and proportional to NIS abundance; 3) targeted impact on a small number of competitors with overlapping niches; and 4) pervasive impact that is disproportionate to NIS abundance and caused by modifications that filter out other species. I developed a statistical test to distinguish these four mechanism scenarios based on plant community rank-abundance curves and then created a scale-independent standardized impact score. Using an example long-term dataset, that has high native plant diversity and an abundance gradient of the invasive vine, <em>Vincetoxicum rossicum</em>, I show that impact resulted in either targeted or pervasive extirpations. Regardless of whether NIS impact is neutral, targeted, or pervasive, the net outcome will be the homogenization of ecosystems and reduced biodiversity at larger scales, perhaps reducing ecosystem resilience. The framework and statistical evaluation of impact presented in this paper provide researchers and managers with an objective approach to quantifying NIS impact and prioritizing species for further management actions.</p>

Linking ecological specialization to its macroevolutionary consequences: An example with passerine nest type
<p>A long-standing hypothesis in evolutionary biology is that the evolution of resource specialization can lead to an evolutionary dead end, where specialists have low diversification rates and limited ability to evolve into generalists. In recent years, advances in comparative methods investigating trait-based differences associated with diversification have enabled more robust tests of this idea and have found mixed support. We test the evolutionary dead end hypothesis by estimating net diversification rate differences associated with nest site specialization among 3,224 species of passerine birds. In particular, we test whether the adoption of hole-nesting, a nest site specialization that decreases predation, results in reduced diversification rates relative to nesting outside of holes. Further, we examine whether evolutionary transitions to the specialist hole-nesting state have been more frequent than transitions out of hole-nesting. Using diversification models that accounted for background rate heterogeneity and different extinction rate scenarios, we found that hole-nesting specialization was not associated with diversification rate differences. Furthermore, contrary to the assumption that specialists rarely evolve into generalists, we found that transitions out of hole-nesting occur more frequently than transitions into hole-nesting. These results suggest that interspecific competition may limit adoption of hole-nesting, but that such competition does not result in limited diversification of hole-nesters. In conjunction with other recent studies using robust comparative methods, our results add to growing evidence that evolutionary dead ends are not a typical outcome of resource specialization.</p>
The linked data ecosystem for SSH and a case study from the cultural heritage domain
<p>Semantic Web, an extension of the current web, focuses on the structure of data. The aim is to develop data structures that will be more effectively processable by computers, in contrast to the limited functionality of the contemporary scriptocentric web. Semantic Web, therefore, aims to transform the web into a global ‘database’ and lead the developments toward the Web of Data. The specifications developed or related to this aim, as well as the processes and rules for achieving it, are known as Linked Data, i.e. (inter)connected data from different sources. Linked Data creates a content-agnostic, as well as software-agnostic ecosystem, which can be used for encoding and publishing all types of information from various domains.</p> <p>The first presentation of this webinar introduces the basic concepts of Linked Data and shows that Linked Data are particularly suitable for Social Sciences and Humanities (SSH) since they do not emphasize metrics and quantifications but conceptualizations and reason. After presenting the paradigm shift introduced by linked data concerning the development of the web, a case study from the cultural heritage domain will be discussed.</p> <p>The second presentation showcases SearchCulture.gr, the Greek cross-domain Cultural Data Aggregator, as a state-of-the-art case, for the use of Linked data in the cultural domain. The National Documentation Centre of Greece (EKT) develops this service, which has collected a growing number of 800.000 digitized Cultural Heritage Objects (CHOs) from 73 cultural institutions. Moreover, it is the Accredited National Aggregator for Europeana having provided more than 580.000 CHOs so far. Addressing metadata heterogeneity has been a key target from the start. Controlled Linked Data vocabularies for item types, historical periods, subjects and persons have been developed over the course of the past years and are being used for the semantic enrichment of the CHOs’ metadata. This presentation addresses the challenges, methodology and tools used over the past 7 years for the process of enriching the aggregated CHOs’ metadata. This process classifies and disambiguates the aggregated data, provides multilinguality and adds significant browse and search functionalities to the portal and, therefore, opens new horizons for SSH research.</p>

Global intraspecific trait-climate relationships for grasses are linked to a species' typical form and function
<p>Plant traits are useful for predicting how species may respond to environmental change and/or influence ecosystem properties. Understanding the extent to which traits vary within species and across climatic gradients is particularly important for understanding how species may respond to climate change. We explored whether climate drives spatial patterns of intraspecific trait variation for three traits (specific leaf area (SLA), plant height, and leaf nitrogen content (Nmass)) across 122 grass species (family: Poaceae) with a combined distribution across six continents. We tested the hypothesis that the sensitivity (i.e., slope) of intraspecific trait responses to climate across space would be related to the species' typical form and function (e.g., leaf economics, stature, and lifespan). We observed both positive and negative intraspecific trait responses to climate with the distribution of slope coefficients across species straddling zero for precipitation, temperature, and climate seasonality. As hypothesized, variation in slope coefficients across species was partially explained by leaf economics and lifespan. For example, acquisitive species with nitrogen-rich leaves grew taller and produced leaves with higher SLA in warmer regions compared to species with low N<sub>mass</sub>. Compared to perennials, annual grasses invested in leaves with higher SLA yet decreased height and N<sub>mass</sub> in regions with high precipitation seasonality. Thus, while the influence of climate on trait expression may at first appear idiosyncratic, variation in trait-climate slope coefficients is at least partially explained by the species' typical form and function. Overall, our results suggest that a species' mean location along one axis of trait variation (e.g., leaf economics) could influence how traits along a separate axis of variation (e.g., plant size) respond to spatial variation in climate.</p>
Data for linked disturbance in the temperate forest: earthworms, deer, and canopy gaps
<p>Despite the large body of theory concerning multiple disturbances, there have been relatively few attempts to test the theoretical assumptions of how and if disturbances interact. Of particular importance is whether disturbance events are linked, as this can influence the probability and intensity of ecological change. Disturbances are linked when one disturbance event increases or decreases the likelihood or extent of another. To this end, we used two long-term, multi-disturbance experiments in northern Wisconsin to determine whether earthworm invasion is linked to canopy gap creation and white-tailed deer browsing. These three disturbances are common and influential within North American temperate forests, making any interactions among them particularly important to understand. We expected both deer and canopy gaps to favor invasive earthworms, particularly species that live close to or on the soil surface. However, we found only partial support for our hypotheses, as both deer exclosures and canopy gaps decreased earthworms in each experiment. Further, earthworm density increased the most over time in areas far from the gap center and in areas with deer present. Deer exclosures primarily decreased <em>Aporrectodea</em> and <em>Lumbricus</em> species, while gaps decreased <em>Dendrobaena</em> and <em>Lumbricus</em> species. Our findings show that earthworm invasion is linked to deer presence and gap-creating disturbances, which provides new insight toward multiple disturbance theory, aboveground-belowground dynamics, and temperate forest management.</p>

Pattern variation is linked to anti-predator colouration in butterfly larvae
<p>Prey animals typically try to avoid being detected and/or advertise to would-be predators that they should be avoided. Both anti-predator strategies primarily rely on colour to succeed, but the specific patterning used is also important. While the role of patterning in camouflage is relatively clear, the design features of aposematic patterns are less well understood. Here, we use a comparative approach to investigate how pattern use varies across a phylogeny of 268 species of cryptic and aposematic butterfly larvae, which also vary in social behaviour. We find that longitudinal stripes are used more frequently by cryptic larvae and that patterns putatively linked to crypsis are more likely to be used by solitary larvae. In contrast, aposematic larvae are more likely to use horizontal bands and spots, but we find no differences in the use of individual pattern elements between solitary and gregarious aposematic species. However, solitary aposematic larvae are more likely to display multiple pattern elements, whereas those with no pattern are more likely to be gregarious. Our study advances our understanding of how pattern variation, colouration and social behaviour co-vary across lepidopteran larvae, and highlights new questions about how patterning affects larval detectability and predator responses to aposematic prey.</p>
